UNIT 6 ASSIGMENT 1 IT Infrastructure Security Policy Purpose of the Network InfrastructureThe Companies values openness and promotes access to a wide range of information; accordingly, the campus information systems have been designed to be as open as possible.
The Companies network consists of: data cables and jacks from the wiring closets to the user’s work station, or wireless access points to a user’s PC; copper and optical data communications cables; Ethernet switches, routers, servers, and peripherals; systems to enable and manage access; and systems to monitor the capacity and maintain the integrity of the network, with the goal to provide high availability and capacity to support the needs of the network users. The reliability, availability and adequate capacity of network resources is critical to the day-to-day function of the Companies.
Each member of the Companies community (students, faculty, staff, and guests) is expected to protect the integrity of the network and to know and adhere to Companies rules, regulations and guidelines for their appropriate use. Regulations that govern personal conduct and use of Companies facilities also apply to the use of network resources. * Components of the Network Infrastructure Policy * Appropriate Use * Unacceptable Use * Access Restrictions * Request for Evaluation
Read this Chapter 2 – Why Security is Needed
Components of the Network Infrastructure Policy * * Connecting Devices to the Network * The campus network is a shared resource. It is therefore necessary to strike a balance between enabling opportunities for teaching and research, and protecting the integrity of network resources. To this end, Companies must be involved in the planning, acquisition, maintenance, and on-going connectivity of all network devices. This will ensure the appropriate network design, interoperability of components and integrity of operation.
If a device is connected to the network infrastructure without prior consultation, Companies cannot guarantee the on-going connectivity and proper operation of the device. * * Wireless Network Equipment The interest and use of wireless networking (802. 11a, 802. 11b & 802. 11g, Wi-Fi) is evolving rapidly. All network use policies apply to the use of wireless LAN technology. Wireless access to Companies resources which will be secured through a central authentication system, except for specific departmental needs.
The company will work with individual departments and colleges to help address their special needs for wireless technology. * * Domain Name Service Internet servers for academic departments or administrative units serving campus related information may need DNS entries set up for the server. Requests for DNS entries will need to be submitted to the Networking unit of Companies for approval. No other DNS server should be setup by other campus units. DNS names will not be given to a server set up for personal use, such as a personal web server.
Any web site served on the web servers maintained by Companies such as www. uww. edu, facstaff. uww. edu, and students. uww. edu will carry the appropriate path names as URL; no DNS name will be given. Occasionally members of the Companies community may sponsor an organization that is loosely affiliated with the Companies. These organizations may be of professional, scholarly, partnership or entrepreneurial nature. Under certain circumstances it may be appropriate for these organizations to hold DNS names other than uww. edu , while hosting them in the Companies domain.
Provided that the use of these domains support the Companies’s mission and are consistent with all applicable Companies policy, Companies may host them within the uww. edu domain. Approval and regular review of these domains will be conducted on a case-by-case basis by the Chancellor and the CIO. Additionally, there are technical criteria that must be met, such as: 1. “Servers in the domain must reside in the McGraw data center. 2. This progress must be listed as the technical contact with the registrar**, so that others are aware of any changes and can respond appropriately. 3.
Only UW-W DNS servers should be specified to the registrar * * Dynamic Host Control Protocol The DHCP service delivers IP information to campus workstations to provide Internet connectivity. The central DHCP service and the management of IP assignments is administered by Companies. No other DHCP service should be set up on campus without prior consultation with Companies, and only to meet specific administrative or academic needs. *Remote Access to Network Resources While web access is sufficient for the majority of Companies educational and business activities there are some instances when direct access to network resources is necessary.
To enable remote access to network resources in a secure manner that protects confidentiality and integrity of Companies and personal information Virtual Private Networking is a method by which a user can access UWW’s internal network via the internet in a secure manner through a firewall or similar security layer. Remote access for some campus services, such as email and library databases, may be addressed in separate campus policies. Authorized users must only connect to the Companies network from computers that conform to the Network Infrastructure Use Policy security requirements.
This includes ensuring that computers are fully patched with the latest operating system updates and have current antivirus software. Appropriate UseListed below are the policies that govern data network access and usage for students, staff and faculty at the Companies of Wisconsin Whitewater. 1. Authorized users Authorized users are (1) current faculty, staff, and students of the Companies; (2) individuals connecting to a public information service supported on the Campus network and (3) others who are specifically authorized to use a particular computing or network resource by the campus unit responsible for the resource. . General Guidelines Those who use the campus network resources are expected to do so responsibly, that is, to comply with state and federal laws, with this and other policies and procedures of the Companies, and with normal standards of professional and personal courtesy and conduct. 3. Security Information security at Companiesis everyone’s responsibility. To maintain security in using the campus network services, it is important to adhere to the following guidelines: * Protect your login ID and password.
Computer accounts, passwords, ids and other types of authorization are assigned to individual users and should not be shared with others. * Be aware that the person to whom an account is assigned will be held accountable for any activity originating from that account. * Do not access data or systems for which you have not been given specific authority. * Take reasonable steps to ensure that your desktop or laptop computer system does not create a security risk when connected to the network, including keeping anti-virus software and operating patches up-to-date. Report security violations. 4. Confidentiality Information stored on computers is considered confidential, whether protected by the computer system or not, unless the owner intentionally makes that information available to other groups or individuals. The Companies of Wisconsin Whitewater takes the position that computer users desire that the information that they store on central and/or campus shared computing resources remain confidential.
While all efforts will be made to ensure confidentiality, users should be aware that data (including e-mail) might, due to software or hardware failure, become accessible to those Companies who are not authorized for that access. Companies personnel may also on occasion have access to such data while performing routine operations or pursuing apparent systems or user problems. No guarantee of complete privacy is made or implied by this policy. Requests for the disclosure of confidential information will be governed by the provisions of the Family Educational Rights and Privacy Act of 1974 (FERPA) and the Wisconsin Open Records Statutes .
All such requests will be honored only when approved by Companies officials who are the legal custodians of the information requested, or when required by state or federal law, or court order. Users found to be copying, modifying, or otherwise accessing information for which they have not been granted permission may be liable to disciplinary action. Unacceptable UseNetwork resources at this Companies may not be used for unlawful activities, commercial purposes not associated with the Companies, or uses that violate other Companies policies or guidelines.
